JPH08281161A - Estimated liquid volume extraction and transfer device - Google Patents

Abstract

PURPOSE: To enable an estimated volume to be transferred automatically by interposing an estimated liquid volume extraction/transfer device between a liquid container and a transfer container, then operating a push button to circulate the air between both containers, and transferring the liquid in the liquid container to the interior of the transfer container. CONSTITUTION: When transferring an estimated volume of liquid B contained in a liquid tank F into a spray can A, the cap 2 of a transfer device is caused to come into contact tightly with the mouthpiece 7 of the liquid tank F. Next, a transparent pipe 22 is inserted into the spray can A and the mouthpiece 6 is closed airtightly using a plug 5. If a closing plate 3 is opened by pressing a push button 4 under this state, the air circulates between the interiors of the liquid tank F and the spray can 2, so that th liquid B in the liquid tank F flows down into the spray can A passing through an opening part 12 and the transparent pipe 22. If the liquid level of the flowing down liquid B' reaches the lower end S of the transparent pipe 22, the circulation of the air is shut off, and the transfer of the liquid B is suspended. After that, the push button 4 is returned to its home position and the transfer device with the opening part 12 closed by the closing plate 3 is removed.

2. Description of the Related Art When transferring a fixed quantity liquid from a liquid container to another container, there is an automatic take-out device as a means for taking out the liquid from the liquid container, but when transferring the taken-out liquid to another container only in a fixed amount. Had to use a measuring tool such as a box.

[0003]

SUMMARY OF THE INVENTION The present invention is intended to provide a fixed quantity liquid extraction / transfer device which can automatically change the fixed quantity from a liquid container to another container.

[0004]

The quantitative solution extracting / transferring device according to the present invention will be described below with reference to FIG. Reference numeral 30 is a quantitative liquid extraction transfer tool, 10 is an extraction member 20 and a transfer member, and both members are connected through a hollow hole. The extraction member 10 is formed as a hollow cylindrical body 11, and a cap 2 having a screw 25 and a sealing material 26 is pivotally attached to the front end of the cylindrical body.

The hollow cylindrical body 11 has an opening 1 of the cylindrical body.
A closing plate 3 for closing 2 is provided via a connecting rod 31, and a push button 4 is provided at the other end of this rod. The closing plate 3 is normally maintained by the spring 14 provided between the push button 4 and the ridge 13 so as to close the opening 12, but by pushing the push button 4 in the direction of the chain line, The opening can be opened by separating the closing plate 3 from the opening 12.

The closing plate 3 is loosely attached to the tip of the connecting rod 31 via the cap nut 32. This loosens the contact with the opening 12 and the sealing property between the rods 31 is O-ring. Reserved by 33. Close plate 3
The sealing performance between the opening 12 and the opening 12 is ensured by the sealing material 15 provided on the end wall surface of the opening. A sealing material 16 such as an O-ring is provided at the tip of the protrusion 13 that contacts the surface of the connecting rod 31.

The transfer member 20 is composed of a hollow body 21 and a transparent tube 22 (transfer tube) which is connected to the hollow body 21. The base portion is connected to the hollow cylindrical body 11, and a common communication hole P for both is provided.
Has been done. In the plastic molding, the hollow bodies 11 and 21 can be formed as a single molding.

At a predetermined position of the transparent tube 22, a stopper 5 is fixed in a hermetically sealed manner. The stopper 5 is formed of a flange 51 and a cylinder 52, and the cylinder 52 is provided with a sealing material 53 such as an O-ring. It is provided. A visible portion 24 having a predetermined width M is formed between the transparent tube 22 and the hollow body 21, and the length from the lower surface of the flange of the plug 5 to the small groove 23 formed at the lower end S of the transparent tube is L. Has been formed.

[0009]

[Function] The cap 2 of the quantitative liquid extraction / transfer tool according to the present invention
By sealingly attaching the plug to the mouthpiece of the liquid container and the stopper 5 to the mouthpiece of the transfer container, a closed space is formed between the liquid container and the quantitative liquid extraction transfer tool and the transfer container. Therefore, if the closing plate 3 is released via the push button 4, the air in the liquid container and the air in the transfer container are circulated, and accordingly, the amount of the liquid until reaching the lower end S of the transparent tube is determined. Filling is performed.

EXAMPLE An example of the present invention is applied to a spray can in a spray can system. The spray can system as a premise will be briefly described below with reference to FIG.

In FIG. 2, reference numeral A is a portable spray can having a function of spraying the liquid B, and E is an air cylinder (pressurizing device) for injecting air from the spray can through the injection valve C. , F is a spray can valve D
Is a liquid tank for injecting the liquid B from the opening after removing the cap K, and the respective injecting functions are achieved through the injecting device between E and C and between F and A. The spray can A is filled with the liquid by removing the cap K. The embodiment of the present invention is an application example in the case of quantitatively transferring the amount of liquid injected into the spray can as the liquid injection tool between the F and D. Regarding the spray can system, Japanese Patent Application Nos. 6-329278 and 6-329279.
The technology is disclosed as an issue.

The embodiment of the present invention will be described below with reference to FIG. In the figure, the procedure for extracting and transferring the liquid is as follows if it is shown as a list. 1. The cap 2 is brought into close contact with the base 7 under the liquid container (liquid tank). 2. The transparent tube 22 is inserted into the spray can (transfer container) A, and the stopper 5 is tightly fitted to the base 6. 3. 3. Push the means rear push button 4 to release the closing plate 3 (see the chain diagram). When the closing plate 3 is released, the air in the liquid container F and the spray can is circulated, and accordingly, the liquid B in the liquid container is circulated.
Flows through the opening 12 and the transparent tube 22 into the spray can. 5. When the liquid level of the downflowing liquid B ′ reaches the lower end S of the transparent tube, the flow of air is interrupted and the outflow of the liquid B from the liquid container is stopped. 6. Return the push button 4 to the original position and close the opening 1
Close 2 7. The cap 2 is removed from the base 7. 8. Remove the stopper 5 from the base 6 of the spray can. Immediately after this separation procedure, air flows in the quantitative liquid extraction / transfer tool and the spray can via the empty groove of the small groove 23, and the liquid in the transfer tool naturally flows down.

In this way, the quantitative solution is transferred (filled) into the spray can A from under the liquid container. The predetermined amount is determined by the length L from the stopper to the lower end of the transparent tube. The present invention is not limited to the above-mentioned embodiment, and the presence or absence of transparency of the shape transparent tube of the extractor and the attachment position of the plug can be designed arbitrarily.

[0014]

As described above, according to the present invention, the quantitative liquid extraction / transfer device is interposed between the liquid container and the transfer container so as to form a closed space, and the push button is operated to allow the air to flow between the both containers. A predetermined amount can be secured by automatically transferring the liquid in the liquid container into the transfer container and controlling the length between the transfer pipe and the stopper. Further, the transfer pipe is a transparent pipe so that a visible portion can be formed, and the filled state of the liquid can be grasped by directly looking at the visible portion.
